from __HAVE_DMA. This will be useful for adding vblank sync support to
sis and tdfx. Rename dma_service to irq_handler, which is more
accurately what it is.
- Fix the #if _HAVE_DMA_IRQ in radeon, r128, mga, i810, i830, gamma to have
the right number of underscores. This may have been a problem in the
case that the server died without doing its DRM_IOCTL_CONTROL to
uninit.
irq handler in DRM(irq_install). Modify all drivers to ensure irq
handler is removed before cleanup and cleanup is called at takedown.
Remove unused buffer private struct fields in i810, i830. Check for
lock on init/cleanup in all drivers except i810/i830. The current DDX
for i810 and i830 doesn't hold the lock on kernel init (FIXME?).
use correct address for ring read pointer writeback (yes, we seem to have
been running with bogus values for the ring read pointer, which
'worked' because the return value of radeon_wait_ring() is never
checked and the ring usually never fills up)
ioctl. The DRM reads them from memory addresses the chip writes to on
updates. Fall back to reading the registers directly with an old DRM.
